The engine 3 may be anysuitable 55 my invention is intended to beemployed. type of internalcombustion engine. I have Cli shown the shaft fO driven thereby us beingprovided with clutch 31 and with change gear bOX These parts may be ofany suitztble and desired construction.

The end or theengine frame 2, opposite that which is hinged, is supportsl on springs as follows: lhe frame has :1 lug" or ear, 21, projectingfrom each side and centrally bored to receive a pin or bolt 2:2, whichis fined to the main truck frame. i l. helical spring 23 is placed, bothabove end below the ear 21, these springs acting to support this end ofthe engine trams, and also to prevent undue rising thereoi when anupward throw is produced by inequalities in the road bed. Normally, thespring which is below theeer 21, carries the loud. The spring 23 whichis above the car 21, prevents undue rising of the engine frame, shoulditbe given an upward throw by inequalities of the track. ln this mannerthe vibrations produced by the operation or the engine are absorbed andare communicated in only a relatively small per cent, to the main truckframe.

The shaft 33, which terms .1- pert or the transmission which is farthestremoved from the engine, has mounted. thereon a gear wheel 3%, whichmeshes with the companion v gear 35, mounted upon a shaft 37. which is'ournaled upon the main truck frame. It is evident that sprocket wheelsand a chain maybe used es a substitute drive.

The shaft 37, upon which the wheel 35 is secured, is a short section ofa transmission mechanism which connects the two axles of the truck. Thissection is journeled in suitable bearings carried by the main trucl:frame. The gears end being; placed adjacent to the hinge E20 connectingthe msin truck frame with the engine ireme, the slig t vibrations due tothe rise and fell oil the opposite end or the engine frame 2- will nothere any serious eiiect in tne transmission of power between the twowheels.

The section 3'? of this transmission line hetween the truck axles isconnected by meens'or uniyerssl couplings with shrtts extending to theearl-est of which the shaft 39 forms a part. These other shuit'ts ateach end, carry a bevel pinion 19. which meshes with the bevel 1"carried by the mile. The type oi": mech nism employed for com nectingthe trans on shaft with the mile is, in 21 large me. l l ted the bevel rto he one the truclr supporting this from the tr springs and inproviding an upper mbunted to swing upon the lower bolster and to whichthe can body is secured.

Both bolsters are provided with an opening surrounding their pivot axis,through which pass the levers and rods which may be needed in order tocontrol the engine and the transmission mechanism. The type ofcontrolling means employed may be anything found suitable and have,therefore, not been illustrated. The her 7 is shown as being symbolic ofa member ot such controlling mechanisms. A preferred type ofconstruction nsists inemploying two ll-besms ilor the main part of thelower bolster. 'lhese 'i-heums are connected at their ends by plates d0,which plates are secured to semi-elliptical, or lest springs 5, bybolts. These springs 5 have their ends secured to shoes 50 which eremounted to have a s ight sliding movement lengthwise of the truck uponthe side here 1 thereof. As the spring is depressed, the ends thereofwill tend to separate slightly. These ends are not fixed to the truckframe so rigidly but that they can move lengthwise thereof enough to socommodate this action. I may also provide it helicelly coiled spring51', which is secured upon the truck frame immediately below the leafspring 5., end which is designed to act as on additional check andsupport for the bolster, when unusual force is applied thereto.

Atthe center of the lower bolster a plate il is secured, this extendingfrom one it beam to the other and having it central opening le and alsobeing provided with acirculer groove on its upper surface adapted toform the swinging pivot between the truck and the ear. The top bolsteri8 is also composed of two Iii-beams suitably secured to gether. Thishas a plate 42 secured to its lower surface and provided with a circularprojection. coinplementul to the groove in the plate 41 and constitutingthe other half of the pivot bearing between the cur and the truclr.
